In a crossover clinical study in subjects with mild or moderate asthma on a stable regimen of asthma medication (n=25), patients received orally inhaled drug 84 mg every 4 hours for a total of 3 doses and placebo. Cough was reported by 60% of subjects following drug administration compared with 0% following placebo. Ten subjects (40%) had temporary FEV1 reductions from baseline (between 15% and 59%), and 4 of these subjects also had a reduction in FEV1 following placebo. Subjects with a reduction in FEV1 remained asymptomatic and did not require rescue treatment.

Fever, altered consciousness, autonomic dysfunction and muscle rigidity are the hallmarks of the neuroleptic malignant syndrome. The neuroleptic malignant syndrome (NMS) is associated with a case fatality rate of about 20%. If withdrawal of dopaminergic therapy is suspected as the cause of NMS, dopaminergic therapy should be restarted. If a neuroleptic agent is suspected as the cause, the neuroleptic agent should be immediately discontinued. For patients with NMS suspected to be due to neuroleptic therapy, consideration should be given to dantrolene (or bromocriptine) administration. Intensive monitoring and supportive care are indicated for all patients with NMS.
Common (1% to 10%): Fall
